Superficial femoral artery injury resulting from intertrochanteric hip fracture fixation by a locked intramedullary nail

Iatrogenic vascular injuries are uncommon during the course of proximal femur surgical procedures. We report the case of an 85-year-old female presenting with an intertrochanteric fracture, treated by anterograde (cephalocondylic) intramedullary nailing (Stryker gamma 3 nail) and complicated by a superficial femoral artery laceration at the level of the distal locking screw. Lower limb traction in adduction and internal rotation on the operating table might put at risk the superficial femoral artery during distal screw drilling and insertion. We therefore recommend returning to the neutral position and reducing lower extremity traction after femoral head screw placing and before final distal screw insertion. This technical precaution should limit the risk of superficial femoral artery injury associated with short-nail anterograde intramedullary nailing.

Tufted hair folliculitis: complete enduring response after treatment with rifampicin

BACKGROUND

A 47-year-old woman presented with erythematous lesions with papules and pustules on her parieto-occipital region that had been present for 8 months. Areas of sclero-atrophic alopecia were evident, whereas at different points tufted hair shafts were coming out from single dilatated follicular ostia. Before our observation, an antibiotic oral therapy with tetracyclines and local with erythromycin had been administered to the patient, with partial improvement and relapse on its suspension.

METHODS

Bacterial culture from pustules showed the development of Staphylococcus aureus. A skin biopsy was done. According to clinical and histopathological findings a diagnosis of tufted hair folliculitis was made and a treatment with oral rifampicin was started at the dosage of 450 mg twice per day.

RESULTS

After 3 weeks of therapy, the pustular lesions regressed completely and after a follow-up of 1 year no relapse was observed.

CONCLUSIONS

Rifampicin is one of the best active antibiotics against S. aureus, which seems to play a role in the pathogenesis of tufted hair folliculitis. Our results, if further confirmed, may suggest a role for rifampicin either for the control of the pustular phase of this rare disorder or to prevent its relapses for a long time.

[Treatment of HCV-associated cryoglobulinemic glomerulonephritis]

HCV-related membranoproliferative glomerulonephritis is the most common cause of hepatitis C-associated renal disease. Its treatment is still under debate and based on scant experimental evidence. The recommended therapeutic strategy depends on the severity of the kidney disease. The first-line treatment for patients with mild to moderate clinical and histological kidney damage is antiviral therapy with pegylated interferon alpha and ribavirin for 48 weeks combined with symptomatic treatment (diuretics, angiotensin converting enzyme inhibitors and angiotensin receptor blockers). In case of severe renal involvement (nephrotic syndrome, nephritic syndrome and/or progressive renal failure, high activity score of glomerulonephritis on light microscopy), the initial treatment may consist of sequential administration of immunosuppressive therapies (plasmapheresis, corticosteroids and cyclophosphamide) and antiviral agents, although no definitive data are yet available from the literature. B-cell depleting agents such as rituximab may be an alternative to conventional therapy in refractory or intolerant patients. Large randomized and controlled clinical trials are needed to establish guidelines for the treatment of HCV-related cryoglobulinemic glomerulonephritis.

[Resistant hypertension in non-dialysis chronic kidney disease]

Resistant hypertension is defined as blood pressure that remains above the target of <140/90 mm Hg in the general population and <130/80 mm Hg in people with diabetes mellitus or chronic kidney disease (CKD) in spite of the use of at least three full-dose antihypertensive drugs including a diuretic, or as blood pressure that reaches the target by means of four or more drugs. Hypertension is a frequent complication in CKD and a determining factor in the progression of renal damage, especially in proteinuric and diabetic patients, as well as contributing to a high cardiovascular risk. Clinical practice guidelines recommend blood pressure levels below 130/80 mm Hg in all CKD patients, but the target is reached in only a small proportion (10-20%), both in nephrology and non-nephrology settings. The resistance to antihypertensive treatment may be considered one of the causes of the poor achievement of blood pressure targets in CKD patients.

Regenerative surgery: use of fat grafting combined with platelet-rich plasma for chronic lower-extremity ulcers

BACKGROUND

The authors present their experience with reconstructive surgery of the lower extremity for chronic ulcers, evaluating the effects related to the use of a platelet-rich plasma combined with fat tissue.

METHODS

A total of 20 patients, 25 to 50 years of age (median age, 40 years), have been managed with platelet gel in the Plastic and Reconstructive Surgery Department at the "Tor Vergata," University of Rome. The patients were affected by both lower-extremity chronic ulcers and vascular disease.

RESULTS

The authors observed that 16 of 20 chronic lower-extremity ulcers reepithelialized during an average of 9.7 weeks, with platelet releasate suspended on a collagen base (platelet-derived wound-healing factor), compared with 2 of 10 similar wounds treated with medication based on hyaluronic acid and collagen. Collectively, these data provide evidence for the clinical use of platelet technology in the healing of both soft and hard tissue wounds.

CONCLUSIONS

Currently, plastic surgery with autogenous fat grafts can be performed for stabilization of chronic lower-extremity ulcers. The objective of this study was, through the presentation of clinical cases, to suggest a therapeutic plan formed by two sequential treatments: acquisition of platelet gel from a small volume of blood (9-18 ml) followed by the Coleman technique for reconstructing the three-dimensional projection and superficial density of tissues. The results proved the efficacy of combining these two treatments, and the satisfaction of the patients confirmed the quality of the results.

Improvement of Durie & Salmon staging for multiple myeloma by adding platelet count as a stratifying variable: a multivariate regression analysis of 163 untreated patients

The presenting clinical features of 163 previously untreated patients with multiple myeloma were correlated with survival duration using univariate and multivariate regression analyses. The univariate proportional hazard analysis ranked the parameters in the following order of importance: platelet count, haemoglobin level (Hb), tumour cell mass stage, lytic bone lesions, creatinine and age. When the individual contribution of each variable was assessed by multivariate regression analysis, platelet count was confirmed to be the dominant feature for prognosis, while clinical stage provided additional information. The introduction of platelet count could then be used to improve the discriminating power of Durie & Salmon staging, by allowing separation of the high-risk group (stages II and III) into a smaller subgroup (22%) of thrombocytopenic patients (less than 150 x 10(9) platelets/l) whose risk of death was actually very high (median survival: 9 months) and a larger subgroup (46%) of patients with normal platelet count and intermediate or standard risk (median survival: 48 months).

High-dose chemoradiotherapy and allogenic bone marrow transplantation in multiple myeloma

17 patients with multiple myeloma (MM) received marrow transplants from their HLA-matched, MLC-negative sibling donors. 9 patients had progressive disease not responding to conventional treatments, while the other 8 patients were rated as responders. The most frequently used conditioning regimen consisted of total body irradiation and high-dose, multi-agent chemotherapy with cyclophosphamide plus either oral melphalan (5 cases) or BCNU (1 case) on both these drugs (7 cases). 12 patients were evaluable for response to BTM: 7 of them (6 responders and 1 with advanced refractory MM) entered complete remission, while 5 had a sustained decrease in tumor mass that ranged between 72% and 93%. 11 patients died of transplant-related causes, 1 of them with signs of progressive disease. The remaining 6 patients are alive and 5 of them maintain a complete remission status 4 to 67 (median 36) months after BMT. It is concluded that therapeutic benefits of transplantation in MM are still offset by the high mortality related to the procedure. A more accurate selection of patients who would most benefit from BMT and performing transplant at an earlier phase of the disease are warranted before major advances can be made in the cure of these patients.

Severely symptomatic craniovertebral junction abnormalities in children: long-term reliability of aggressive management

OBJECTIVES

The treatment of symptomatic cranio-vertebral junction (CVJ) instability in children affected by CVJ abnormalities is a challenge. A series of severely symptomatic children has been reviewed to understand the controversial long-term effectiveness of the aggressive management of CVJ abnormalities, in terms of clinical improvement, spinal stability and growth.

METHODS

Three Down syndrome patients, 1 with mucopolysaccharidosis and 1 with os odontoideum (range 3-6 years old) with a CVJ instability determining spinal cord compression with severe neurological deficits (the patients presented at admission a Ranawat III A/III B neurological condition), were consecutively treated at our institution. Medical records, imaging studies, adopted surgical techniques and long-term results were reviewed. Details of the presenting symptoms, clinical and radiological signs were compared to the signs and symptoms at follow-up.

RESULTS

The perioperative use of an halo-orthosis, the operative techniques and the timing of rehabilitation were always tailored to the patient's anatomical features. All the patients showed remarkable neurological improvements, along with construct stability and bone fusion without abnormalities of the developing spine.

CONCLUSIONS

Considering the effective long-term results, we recommend, even in severely symptomatic children with CVJ abnormalities, a multidisciplinary aggressive tailored treatment of instability with rigid internal fixation.

[Erythropoiesis-stimulating agents in chronic kidney disease: which route of administration?]

In the last twenty years, erythropoiesis-stimulating agents (ESAs) have improved the management of renal anemia, with significant amelioration of quality of life in patients on hemodialysis. ESAs can be administered both intravenously and subcutaneously. In predialysis chronic kidney disease and in peritoneal dialysis, the administration route is necessarily subcutaneous. In hemodialysis the intravenous route was initially preferred because of the presence of ready vascular access for drug administration. Subsequent studies have demonstrated that the subcutaneous route allowed the achievement of optimal levels of hemoglobin with a reduction of mean administered dose, number of injections, and costs. A few years ago, the finding of a higher risk of pure red cell aplasia associated with subcutaneous administration of epoetin reopened the debate about the route of administration. We here review the studies on the preferable route of administration of epoetin and darbepoetin- alpha, in terms of efficacy and safety, and take a look at future perspectives.

Outcome analysis of breast cancer patients receiving breast-conserving surgery in Southern Italy

The purpose of the current analysis was to evaluate the outcome of patients enrolled at the National Cancer Institute of Naples between 1997 and 2000, who underwent breast-conserving surgery. Between January 1997 and December 2000, 946 patients had been diagnosed with T1 or T2 (<3 cm) breast carcinoma. At the time of the present analysis (31-12-2005), all patients had been followed for >5 years. A Cox proportional hazards model was performed. Overall, 7-year Locoregional Relapse-free survival (LRFS) and Distant Relapse-free Survival (DRFS) rates were 95.9% and 88.4%, respectively. Seven-year DRFS was 91.2% and 79.3% in T1 and T2 stage, respectively (p<0.0001). Multivariate Cox analysis indicated that number of positive lymph-nodes and hormone receptor status were significantly associated with prognosis. Our findings confirm that early diagnosed breast cancer, treated with breast-conserving surgery, is associated with a very good prognosis in patients referred to an Institution which may be considered as representative of similar Cancer Institutes of Southern Italy. The risk of local relapse was found to be very low (4%), although a longer follow-up is needed to draw definitive conclusions.

Alternative techniques in reconstructive surgery: bone-anchored extraoral implants for burn cases

BACKGROUND

The authors present their experience with the use of extraoral implants for reconstruction of the ear area after burns. The first step of the protocol includes positioning of implants in the mastoid process. The second step, after 3 to 4 months, is to realize the auricle prosthesis and apply it. Extraoral, bone-integrated implants offer low surgical risks and few postsurgical complications, leading to optimal aesthetic results, mainly in the ear area. Compared with traditional surgery techniques, the aesthetic results are better, with less surgery, possibly only two surgery sessions. Adhesive prostheses can be placed without the usual local irritation, and a more correct positioning can be obtained.

METHODS

For this study, two female patients, treated from December 2001 to January 2005, were selected to receive auricle epitheses. In the authors' experience, 79% of case reporting describes the creation of this epithesis type. The patient age has a range of 26 years. The two study patients initially had the same diagnosis: burns of the auricle-temporal region.

RESULTS

In all cases, a good aesthetic result was obtained.

CONCLUSION

The authors believe that bone-anchored implants for the treatment of auricle burns is a valid and brilliant technique that complements traditional reconstructive procedures. The advantages are the low incidence of long-term complications and the possibility of obtaining excellent aesthetic lasting results even for very complicated cases that would not have been solved in the past.

Conservative management of cervical ectopic pregnancy: case report and review of literature

PURPOSE OF INVESTIGATION

The aim of the study is to describe the management of a case of cervical ectopic pregnancy at six weeks.

CASE

A 34-year-old patient presented with six weeks of amenorrhea and a cervical pregnancy diagnosed by transvaginal ultrasound. Obstetrical anamnesis showed previous cesarean section and celiac disease as medical complications. At six weeks and one day 50 mg intramuscular methotrexate (MTX) was started and repeated three days later. At six weeks + six days the patient had vaginal bleeding so she was submitted to an emergency surgical procedure consisting of dilatation and curettage followed by a Foley balloon tamponade, which was gradually deflated and removed after two days.

CONCLUSION

Early diagnosis and an appropriate MTX regimen in combination with adjuvant conservative procedures allow successful treatment of a cervical pregnancy, preserving the uterus and future reproductive outcome. However further studies are needed to define the best approach for management of cervical pregnancy.

Asymptomatic lacrimal flow abnormalities in patients with septal deviations and turbinate hypertrophy

BACKGROUND

This study aimed to investigate the lacrimal flow in patients affected by septal deviations and turbinate hypertrophy and to evaluate changes after rhinoseptoplasty with dacryocystography (DCT) and computed tomographic dacryocystography (CT-DCT).

METHODS

The study prospectively recruited patients having septal deviations with or without turbinate hypertrophy who underwent surgical evaluation for correction of their respiratory symptoms and were not referred for epiphora. Patients were excluded if they had undergone surgery for cranial vault defects or had experienced septal deviations after traumatic accidents. All patients were studied with DCT and CT-DCT preoperatively and postoperatively.

RESULTS

A total of 24 patients (10 men and 14 women) were recruited for the study. Of these patients, 11 (45.8%) had a reduced flow of the medium contrast due to a partial obstruction at the level of the internal ostium. All 11 patients had septal deviations and turbinate hypertrophy, whereas 8 patients had a unilateral obstruction (72.7%), and 3 patients had a bilateral obstruction (27.3%). All flows were corrected after surgery.

CONCLUSIONS

The safe and well-tolerated radiologic techniques performed in this study provided detailed imaging of the lacrimal outflow system. A high incidence of partial obstruction to the internal ostium was found in patients with septal deviations, turbinate hypertrophy, and no lacrimal symptoms, suggesting a frequent presymptomatic condition.

Bone-anchored implant in cosmetic finger reconstruction

The majority of the patients, who underwent amputation of one or more fingers or present congenital absence of some phalanges, can be treated by microsurgical reconstruction. Several reconstructive techniques are available, but in some cases the use of osseous-integrated implants to anchor silicon digital prosthesis is a valid alternative. We present one case, a 27 years old male, affected by congenital hypoplasia of the second finger of the right hand who underwent reconstruction by prosthesis and extraoral bone-anchored implant.
